I often rent a car
with my US credit card which covers me for auto insurance. This is the main
reason I do that versus paying in euros locally. On my recent visit to
Europecar at the Dublin city center location the agent told me that I need to have a letter from the bank proving
my insurance coverage. I responded the
way I always do when rental companies ask this, that it is covered by
my credit card company. This is very common for card companies to do in the US.
It is one of the perks they offer to get people using the cards for rentals.
This time however the agent working at the counter didn't accept that as an
answer. He told me that when I received the confirmation from the booking it
said that I need to bring it. It didn't say anything about insurance proof as you can see by the screenshot here.
